Moulded and mycotoxin containing barley was incorporated into the diets for laying hens to study the effects on performance and health. Health indicators were different blood plasma parameters and liver vitamin A and E levels. A total of 30 hens were fed 3 diets, one supplemented with 30% of toxin-free and two with differently moulded barley from 1997 and 1998 for 7 weeks. The moulded diets contained low to moderate concentrations of ochratoxin A, zearalenone, deoxynivalenol and nivalenol. Inclusion of mouldy barley in the diets had an adverse effect on feed intake, feed conversion, digestibility of nutrients, egg production and egg quality. Plasma alkaline phosphatase was increased and certain biochemical blood parameters (bilirubin, uric acid, chlorine, protein, albumin, vitamin A) were also higher or changed compared to control. The ochratoxin A contamination although relatively low could have contributed to some of these effects as well as reduced intake of feed. The higher mould contamination and an unidentified cell-toxic constituent in the diet containing barley from 1998 can probably also explain the more marked effects from this diet.
将含有霉菌和霉菌毒素的大麦添加到蛋鸡日粮中，以研究其对生产性能和健康的影响。健康指标包括不同的血浆参数以及肝脏中维生素A和E的水平。总共30只母鸡被饲喂3种日粮，一种添加30%无毒素大麦，另外两种分别添加1997年和1998年不同程度霉变的大麦，为期7周。霉变日粮中含有低至中等浓度的赭曲霉毒素A、玉米赤霉烯酮、脱氧雪腐镰刀菌烯醇和雪腐镰刀菌烯醇。日粮中添加霉变大麦对采食量、饲料转化率、养分消化率、产蛋量和蛋品质均有不利影响。与对照组相比，血浆碱性磷酸酶升高，某些血液生化参数（胆红素、尿酸、氯、蛋白质、白蛋白、维生素A）也更高或发生了变化。尽管赭曲霉毒素A污染相对较低，但可能也导致了其中一些影响以及采食量下降。1998年含大麦日粮中更高的霉菌污染和一种不明细胞毒性成分，可能也解释了该日粮产生更明显影响的原因。
